专利说明:

The invention relates to chemical plant protection products, namely, herbicides containing active substances and auxiliary components.
Herbicidal agents are known, containing various pyrazole derivatives as active substances. These include, for example, an agent based on 1-alkyl-3 aryl-α-alkoxycarbonyl pyrazole, which also contains the auxiliary components of the sodium salt of diisobutylnaphthalene-o, sulfonic acid, the sodium salt of ligninsulfonic acid, and silica gel l.
However, known agents are not sufficiently effective in relation to a whole variety of weed plants. In addition, in effective doses, they damage some cultivated plants.
The purpose of the invention is to enhance the terbicidal activity of the agent based on the pyrazole derivative.
This goal is achieved by a terbicidal agent containing the active substance - a pyrazole derivative of the general formula

where R is aodorod, acetyl, chloroacetyl, methoxyacetyl, methoxycarbonyl or phenoxycarbonyl;
R is phenyl, which can have 1 or 2 substituents from the group of fluorine,
15 chlorine of bromine, cyano, nitro, methyl, methoxy or trifluoromethyl, 2,6-dichloropyridyl-, furyl or thienyl, in a weight ratio with diisobutylnaphthalene-o-sulfo-20 sodium salt, sodium salt of lignin-sulfonic acid and silicate, equal to 20 : 17: 60 respectively.
The proposed agent is prepared by simply mixing the ingredients included in its ingredients. Active substances of the general formula (I) are prepared in various ways, for example, by reaction a; 2-aroyl-3-methylaminocrotonic acid kilo ester, with hydrazine hydrate or by the interaction of 2-aroyl-acetoacetic esters with hydrazine hydrate. They can be synthesized in several other ways. Table. 1 shows the active substances of the general formula (1) and examples illustrating the effectiveness of the proposed herbicidal agent in comparison with the known, containing as active substances 1 - methi-3- (3-trifluoromethylphenyl) - methoxycarbonylpyrazole (compound A) and 1- methyl-3-phenyl-β-ethoxycarbonylpyrazole (compound B) Experimental plants are grown in 300-cm plastic pots on a clay-sandy culture substrate with 1.5 humus. Seeds of experimental plants are shallowly sown, and for post-emergence processing they are grown to a height of 3-10 cm. Some species of experimental plants are planted in individual vessels before germination, and then transplanted into the pots mentioned above. Treatment with a herbicide containing 20 weight.h. active substance (specified in table. 2-5) 5 weight.h. sodium salt diizs utilnaphalt5-sulfonic acid, 17 weight.h. sodium salt of ligninsulfonate and 60 weight.h. silica gel, carried out after germination. The herbicide is applied in the form of an aqueous preparation, which is sprayed on the plants with the help of nozzles. The experiments were carried out in a greenhouse at C, depending on the type of plant, for 3-6 weeks. During this time, the plants are cared for and their response to treatment with the herbicide is evaluated. The assessment is carried out on a scale from 1 to 100, with O being no damage or normal shoot, and 100 plants have not sprouted or at least the shoots above the ground have completely died off. The results of the post-emergence treatment with the active substances of various plants are summarized in Table. 2-5. Table 1
